WATER-ELEVATOR.

Specification of Letters Patent.

Patented Sept. 9, 1913.

Application led September 5, 1911. Serial No. 647,702.

To all 'whom 15 may concern.'

Be it known t-hat I, HENRY COLE, a citizen of the United States, residing in the city and county of Denver and State of Colo `ado, have invented certain new and useful Improvements in IVater-Elevators; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to certain improvements in water-elevators, over my United States Letters Patent issued to me November 27th, 1906, Number 836865.

The object of my invention resides in the construction of a water-elevator for quickly and effectively raising quantities of water for irrigation, and other similar purposes.

Another Object of my invention resides in the provision, of mechanism for preventing the buckets from being carried downwardly into the well under the influence of the extra weight incident to the quantity of water contained in the buckets on the upward moving side of the conveyer, after the power for operating the conveyor has been discontinued.

The necessity for a cheap and efficient water-elevating machine has been keenly felt in arid districts where irrigation is necessary and where plenty of water is located a few feet below the surface. In these districts where there is seldom any rainfall, it is not unusual to find an ample supply of water underneath the surface, suiiicient for irrigating a considerable area surrounding the place where the well is sunk, and in such districts my water-elevating device will enable the water to be raised to the surface in a simple, inexpensive, and efficient manner.

Having set forth the objects of my improved water-elevator I will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In the drawing :WFigure 1, is a side elevation of my improved water-elevator in position for use. Fig. 2, is a top plan view of my improved waterelevator. Fig. 3, is a top plan view of a trough employed in connection with my improved waterelevator. Fig. 1, is an end view of a bucket employed with my waterelevator, illustrating the same attached to a fragment of the conveyor and showing the position the bucket occupies on the upward moving side of the conveyor. F ig'. 5, is a similar View showing the position the bucket occupies on the downward moving side of the conveyer. Fig. 6 is a vertical section taken on the line 6 6 Fig. 1, looking in the direction of the arrow. Fig. 7 is a detail View of the U-shaped member for holding the brake in the inoperative position.

The same reference characters indicate the same parts in all the views.

Let the numeral -i designate cach of two suitable spaced endless sprocket-chains, engaging' a pair of upper sprocket wheels 6, and a pair of lower sprocket wheels, only one of the latter being shown in the drawing and designated by the numeral 7. These chains 4 are connected by buckets 8, whose extremities are provided with spindles 9, journaled in lugs 10, mounted upon the chains. Each bucket is open at the top, and its bottom is of oval shape. r1`he spindles 9 of each bucket are near the top of the latter, whereby the buckets have a normal tendency to occupy the vertical position, or a position with their open sides uppermost, since the bottom of the buckets is farther from the pivotal center than the top.

The upper sprocket wheels 6 are made fast to a shaft 12, suitably journaled on supports 13, secured to a frame-work 111 by means of bolts 15. r1 he supports 13 are provided at their upper extremities with U- shaped slots 16, which receive the extremities of the shaft 1Q.

Upon the shaft 12, two suitably spaced disks 17 are made fast, the peripheries of which are successively engaged by the opposite extremities of the buckets, during the travel of the chains ii composing the conveyer. These disks 17 act upon the buckets to cause the latter to turn upon their journals for dumping' the water therefrom. As cach bucket passes over the disks 17, and assume a position corresponding with the downward moving side of the conveyor, the same becomes tilted to a horizontal position, and stops, or pins 1S, mol'lnted on the buckets engage the chains flfor maintaining the buckets in the horizontal position. Now as the buckets or, the downward moving side of the conveyer, reach the lower sprocket wheels and begin to pass around the said wheels, the buckets occupy a position to scoop up wat-er from the well, and as each bucket assumes the upward moving side of the conveyer, the same finds its center' of gravity, and turns upon its journals to the vertical position, or a position with its open side uppermost. Upon the opposite 'eX- tremities of each bucket, and on the lower portion thereof, are mounted pins 19 which engage the chains al when the buckets are in the vertical position, or o-n the upward moving side of the conveyer, whereby the buckets are held to a certain extent against rocking during their upward travel.

Made fast to the opposite extremities of nthe shaft 12 are two drive-wheels 20, which respectively engage relative small wheels 21 suitably journaled as shown at 22. Each of the wheels 21 is provided with a groove 23 in its periphery into which grooves the peripheries of the wheels 20 respectively fit.

Mounted upon the frame work 14- on opposite sides thereof is arranged a brake mechanism, which, l will designate in its entirety by the reference character 2li. This 'brake mechanism consists of a flat shoe 25, secured at one extremity to one member 26 of lan angle member, the other member 27 of the angle member being perforated. A rod 28 passes through the perforation of t-he member 27, the opposite eX- 'tremity of the said rod being supported by an anglemember 29 secured to the frru'nen work 14. This rod 28 is mounted to have la sliding movement in the angle member or `support 29, while the member 27 is rigidly secured to the rod 28. interposed between the member '27 and the member 29 and surrounding thc rod 2S, is a coil spring yBO, which acts upon the member 27, to cause the shoe 25 to wedge in between the wheels 2Ov and 21, u'fhereby a friction is created suli'iicient Yto prevent, the buckets on the upward moving side of the conveyer, from Acausing backward travel of the said buckets under the influence of the weight of the water contained therein. ln order to retain the shoe 25 out of engagement with the `wheels 20 and 21, l provide a member 31, which I insert between the head 32 of the rod 28, and the angle member 29, and since the shoe 25 is connected to move with the rod, the said shoe is held out of engagement with the two wheels against the tension of the spring 30. rliis member 31 is provided with a U-shaped part which straddles the rod 28. Now in order to set the brake it is only necessary to remove the member 31 from between the head 32 of the rod and the member 29 whereby the spring acting on the member 27, causes the shoe 25 to move into wedging engagement with the wheel. .2O

ment of the buckets after the driving power has been shut oli".

@n the top of the frame-work 14, l mount a specially constructed trough designated in entirety by the reference character rhis trough is provided with a centrally located opening 3l, on opposite sides of which are arranged parallel troughs and 3G communicating with each other by means of channels 37. rThe buckets in their upward travel pass through the opening 34 in the trough and they pass over the disks 17 empty tl its their contents into the tro-ugh 35, the water thence flowing in the direction of the arrows through the channels 37, into the rough 36, from which it is discharged through a pipe 38, leading to any desired place.

An important feature of my invention essential to the eective operation of a water elevator of this character will now be described.

By referring to Fig. 1, of the drawing it will be noted that the wheels 2O ride respectively upon the wheels 21 and lthatthe journals of the wheels 20 are supported slightly above the bottom of the journal boxes 16 as shown at stl, whereby the wheels 2() are permitted to rest entirely upon the wheels 21. Vlhe object of this construction is to lessen. the resistance incident to friction usually present where many bearing parts areI employed. By virtue of the construction heretofore described only a miuinuun amount of driving power is required for operating the elevator. rlhe weight of the conveyer and buckets and also the water contained in the buckets on the upward moving side of the conveyer is supported entirely by the wheels 21, instead of by the shaft 12, thus the friction incident to the journal of this shaft is entirely relieved from the journal box 16, and transferred to the wheels 20 and 2,1 which do away almost entirely with 'any friction. Suitable ball-bearings a5 may be arranged in the frame 14 in engagement with the shaft 22 in order vto relieve the friction from the shaft.

erom the foregoing description, the use and operation of my improved 1waterelevator will be readily understood.

Power is transmitted to my improved water-elevator through the medium of a belt l0, to a drive wheel'39 keyed upon the Vshaft 12, whereby the shaft 12 is actuated 'to cause the endless chains 4 to travel over the upper spocket-wheels 6, and lower sprocket wheels 7, carrying the bucketsS therewith. The buckets 8 on reaching their upward' limit of movement, are caused to empty their contents in the trough 35, from which trough the water takes the course heretofore described. Now whenever the driving power and 21 and thus prevent rearward movei is shut off, the brake 241 can be set as heretofore explained, and thus the buckets on the upward moving side of the conveyor will be held against moving rearward.
